Abstract: Altermagnetism is an unconventional form of magnetic order characterized by spin-split electronic bands and zero net magnetization. Here, the authors utilize a variational Monte Carlo approach to reveal the emergence of $d$-wave altermagnetism in the Hubbard model on the Shastry-Sutherland lattice and demonstrate how strong electronic correlations manifest in the metal-insulator transition. The calculation of photoemission spectral functions highlights the presence of altermagnetic Zeeman splitting, also in the Mott insulating phase (and upon doping).
